JOlNERS PLANE.

SPECIFICATION forming part of Letters Patent No. 504,562, datedSeptember 5, 1893.

Application filed April 15,1893.

To all whom it may concern.-

Be it known that 1, JOHN ill. COLE, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Joiners Planes; and I dohereby declare that the following is a full, clear, and exactdescription of the invention,which will enable others skilled in the artto which it appertains to make and use the same.

My invention relates to improvements in joiners planes, and theinvention consists in the construction of a plane substantially as shownand described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal centralsectional view of a plane equipped with myimprovements. Fig. 2 is aperspective View of the plane irons with the parts which are permanentlyattached thereto. Fig. 8 is a perspective view of the metal bed which isseated centrally in a recess in the stock, as seen in Fig. 1, and Figetis a view of a modification of the invention in which an ordinary chiselis shown as being held with mechanism corresponding to the holdingmechanism for the bit in Fig. 2, and as hereinafter more fullydescribed.

Arepresents the stock of the plane, and B is a bed which is seatedcentrally in the body of the stock and fastened thereto by short screws7) so as to make a firm and rigid seat for the attachment of the otherparts. Connection is made with this bed for the bit or plane iron 0 bymeans of the substantially H shaped holder D, secured to the bit C andthe cap E through the slot d by means of a screw 6, Fig. 1. The bed Bhas ledges or ribs 5 on its inside along its lower portion which areengaged by the holder D in the relation and manner shown moreparticularly in Fig. 1. This engagement is made by placing the saidholder into the recess or opening above the said ledges and then slidingthe holder down under the ledges as far as may be necessary, and whenthus introduced the said irons C and E and the holder D are firmlyfastened by means of the thumb screw F at the top of the bit or iron C,which passes through the said bit and bears upon the adjustable bracketG at its inner end. This bracket has a depression or recess g intoSerial No. 470,425. (No model.)

which the said screw F projects, and by reason of which and the bearingagainst the ledges I) through the holder D the bit is prevented frombecoming displaced after it has been adjusted and fastened.

For convenience of fastening the screw F in the bit and to give thedesired bearing for the screw, I insert a threaded plug 7L through thehole in said bit and fasten the same by means of a nut h, the threadedscrew it thus affording a long threaded bearing on its inside for thescrew F. These two parts hand h of course maybe reversed and the screw hmay have a head upon the outside and the nut be placed upon the insideof the bit.

The bracket G is adapted to slide between the sides of the bed B, andupon the ledges of the bed immediately beneath the same, and it has aprojection g with a threaded hole adapted to receive the thumb screw K,which is supported in the webs of the bed 13, and is adapted to berotated within its bearings. Then by turning the screw K the saidbracket is carried gradually up or down upon the said bed and with itthe parts shown in Fig. 2, when the said parts are sufficiently releasedto permit of such adjustment. Such release of course is effected throughthe thumb screw F, which serves to tighten them. This screw may beloosened enough to effect the finest needed adjustment of the bit forcutting deeper or shallower, as may be required, and when thisadjustment is accomplished the bit is again fastened by means of thescrew F and all the parts are in readiness for use. It will be noticedthat by this construction I dispense entirely with the usual clampingplate on the face of the bit, and which is usually arranged to overlapthe cap E some distance above. The bed and the parts shown in Fig. 3 aredesigned to remain fixtures within the stock A while the parts shown inFig. 2 are bodily removable when connected as there shown, by simplyreleasing the thumb screw F so as to detach it from the bed.

Having the plane constructed with the parts shown in Fig. 3, and withthose shown in Fig. 2 removed, I have a construction remaining which isespecially adapted to attach an ordinary chisel L, shown in Fig, 4. Itis often desirable when a groove of narrow width is to be out, or achannel plowed, to have a construction which will enable a chisel ofgreater or less width of edge to be placed on the plane to cut acorrespondingly narrow channel. My construction is especially adapted tothis conversion of the tool, and by means of the stirrup M having ascrew m to engage the shank of the chisel, and a holder N constructed asshown to engage the body of the chisel, I am enabled to use a chisel aseffectually as if the plane were originally made for this purpose alone.The holder N takes the place of the holder D in the structure, and has aset screw 12. to bear down upon the chisel and fix it to the holder, thesame as the screw e in Fig. 1. The stirrup M has a slight projection mon its bottom adapted to engage in the bracket G where the screw Fengages in Fig. 1. The plane may, therefore, be converted from the useof one tool to another with ease and facility, and it is therefore givena range of usefulness which makes it altogether a desirableconstruction.

The construction and operation of the parts will be clearly understoodfrom the foregoing description and need notbe more particularly enteredinto here.

In lieu of the chisel here shown any equivalent cutter or bit may beused, and a very narrow bit, or one the full Width of the bed, or ofintermediate size, can be adopted.

hen for any reason it is desired to remove the cap E from the bit, as isthe case when the bit is to be ground, it is onlynecessary to loosen thescrew e, so that the holder D can be turned in line with the slot in thebit, and then the cap and holder are movable together.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A plane provided with a suitable bed having ledges longitudinal onits inside, a separate holder for the bit engaging said ledges,adjusting mechanism at the upper end of the bit to fasten the bit, andan adjustable bracket or seat on which said mechanism is held,substantially as set forth.

2. The construction herein described consisting of a separate bed fixedin the plane stock and having inside ledges, a separate holder for theplane iron or bit locking on said ledges, a longitudinally adjustablebracket at the top of said bed, and a fastening device for the planeiron or bit bearing upon said bracket, substantially as set forth.

3. The plane having a separate bed fixed centrally therein, said bedhaving longitudinal ribs or ledges upon its inside and a holder andscrew to fasten the bit to said ledges, in combination with anadjustable bracket at the upper end of the bit provided with anadjusting screw and fastening and adjusting mechanism for the upper endof the bit rest in g upon the said bracket, substantially as set forth.

4. The plane stock having a metallic bed fixed therein and a bracket atits upper end adjustable in said bed, in combination with the bit, asubstantially H shaped holder and a screw to secure said bit between itsends to the bed, and a screw in the upper end of the bit bearing uponsaid adjustable bracket, substantially as set forth.

5. The stock and the bed fastened in the stock and provided with ledgesonits inside, a holder for the bit constructed to engage and slide onsaid ledges and to secure the bit, in combination with a bracket in theupper end of the bed, and a screw to adjust the bracket, a threadedbearing in the upper end of the bit and a thumb screw in said bearingengaging said bracket, substantially as set forth.

Witness my hand to the foregoing specification this 5th day of April,1893.
